To ensure that the web application using HTTPS on port 6443 is both reachable and decrypted by Netskope, the correct action is toenable “Steer non-standard ports” in the steering configuration and add the domain and port as a new non-standard port. This is because Netskope’s default configuration steers standard HTTP/HTTPS traffic, typically on ports 80 and 443.Since port 6443 is a non-standard port for HTTPS traffic, it requires explicit configuration to be steered through Netskope1.

References: The process for configuring non-standard ports in Netskope is detailed in the Netskope Knowledge Portal, which provides step-by-step instructions on how to steer HTTP(S) traffic over non-standard ports1. This includes adding the specific non-standard port number in the steering configuration to ensure that traffic to and from that port is properly handled by Netskope.

• When a user is on-premises at the enterprise and accesses an application that is IP restricted, the source IP for traffic to this application is the Enterprise Egress IPv4 address.
• The Enterprise Egress IP represents the external IP address of the enterprise network as seen by external services or applications.
• This IP address is used for communication between the user’s device and external resources, including applications that are IP restricted. References:
• The answer is based on general knowledge of networking concepts and how IP addresses are used in enterprise environments.

The issue is likely caused bya missing group name in the SAML response (A). When access to Microsoft 365 from unmanaged devices is not blocked as expected, despite having a policy in place, it often indicates that the SAML assertion is not correctly identifying the user as a member of the restricted group. In this case, the “marketing-users” group name should be present in the SAML response to enforce the policy that blocks login activity for this group. If the group name is missing, the policy will not apply, and users will not be blocked as intended.

References: This explanation is consistent with the configuration requirements for access control using SAML responses, as detailed in Netskope’s documentation on Reverse Proxy and SAML integration1.

To validate that the GRE tunnel is configured correctly and that traffic is flowing to Netskope, the correct statements are:

• A: You can use your local router or network device to verify that keepalives are being received and traffic is flowing to Netskope. This is a standard method for checking the health and activity of a GRE tunnel.
• C: You can verify that the tunnel is up and receiving traffic in the Netskope UI under Settings > Security Cloud Platform > GRE. This is a feature provided by Netskope to monitor the status of GRE tunnels directly from the Netskope interface12.

Statement B is incorrect because Netskope provides its own tools for monitoring the status of the tunnel. Statement D is incorrect because the Netskope Trust portal provides information on the overall service status and updates, not specific tunnel status3.

References: The references for these answers can be found in the Netskope Knowledge Portal, which provides detailed guidance on configuring and validating GRE tunnels12. Additionally, the Netskope Community Forum offers insights and solutions for deploying and monitoring GRE tunnels

To extract events and alerts from the Netskope Security Cloud platform and integrate them with a SIEM (Security Information and Event Management) solution, you can utilize the following supported methods:

• Cloud Log Shipper (CLS):

For devices not owned by the organization, using an explicit proxy along with the Netskope Client is the best approach to steer traffic for inspection. This method allows for granular control over the traffic, ensuring that only the traffic destined for the company’s instance of Microsoft 365 is inspected by Netskope. The explicit proxy configuration can be applied regardless of whether the users are on-premises or off-premises, providing a consistent steering mechanism for all users.

References: The steering configuration for non-owned devices and the use of explicit proxy in conjunction with the Netskope Client are detailed in the Netskope Knowledge Portal. The portal provides guidelines on how to set up steering configurations to direct traffic from end users to the Netskope Cloud for real-time analysis, which is applicable for both managed and unmanaged devices1

When deploying Netskope and steering all traffic, if you find that the Real-time Protection policies for Microsoft OneDrive are not being enforced, the likely issue is with the default steering exceptions. To resolve this, you should remove the default steering exception for domains ©. This is because the default exceptions may include domains related to Microsoft services, which could prevent the Real-time Protection policies from being applied to traffic directed towards OneDrive. By removing these exceptions, you ensure that all traffic, including that to OneDrive, is subject to the policies you have set up.

References: This recommendation is based on best practices for configuring Real-time Protection policies in Netskope, as outlined in their documentation, which suggests that exceptions should be carefully managed to ensure that security policies are enforced as intended

The reason for the activity being NULL in this scenario is likely becausea user accessed a static Web page.In Netskope’s Advanced Analytics, when the activity is reported as NULL, it often indicates that there was no dynamic interaction or transaction to record, which is typical when a static web page is accessed1. Static web pages do not generate the kind of events or activities that are tracked by policies, hence they appear as NULL in the activity field.

References: This explanation is supported by the Netskope Knowledge Portal, which mentions that applications fields with null values indicate incidents generated from web traffic, such as accessing static web pages2.Further information on interpreting NULL values in Advanced Analytics reports can be found in the Netskope documentation1.

In the scenario where CASB traffic steering is enabled using the Netskope Client without a Real-time Protection policy being activated, the default behavior of the traffic is toallow and log it (B). This means that the traffic will not be blocked; instead, it will be permitted to pass through and will be recorded for monitoring and analysis purposes.This default setting ensures visibility into the traffic and user activities without immediately enforcing a block, allowing for a period of observation and policy tuning before potentially more restrictive actions are taken1.

References: The default behavior of traffic steering in Netskope, including the logging of allowed traffic, is detailed in Netskope’s best practices and community discussions on Real-time Protection policies1.

The reason for using Netskope Cloud Risk Exchange in this scenario is toautomate service tickets from alerts of interest. Netskope Cloud Risk Exchange (CRE) is designed to ingest user, device, and application risk scores, creating a dashboard view of contributors to your company’s overall risk score and trend. One of the key functionalities of CRE is to trigger risk-reducing actions through business rules that are tuned to a weighted score.Automating service tickets from alerts of interest is a part of this functionality, as it allows for the automatic creation of tickets in response to specific alerts, streamlining the process of addressing potential security issues12.

References: The use cases for Netskope Cloud Risk Exchange, including the automation of service tickets, can be found in the official Netskope resources1.Further information on how to integrate and utilize Netskope Cloud Risk Exchange for automating service tickets can be found in the Netskope Knowledge Portal3.

When integrating a third-party Data Loss Prevention (DLP) engine that requires ICAP, the Netskope platform component that must be configured is the Netskope Adapter. The Netskope Adapter is designed to facilitate the integration of Netskope with various third-party tools and services, including DLP engines that use ICAP for communication. By configuring the Netskope Adapter, you can ensure that the third-party DLP engine can communicate effectively with the Netskope platform to provide comprehensive data protection.

References: This information is based on the integration capabilities of the Netskope platform, which includes the use of Netskope Adapters for third-party integrations as detailed in the Netskope Knowledge Portal1 and the Netskope Data Loss Prevention (DLP) documentation2

For a server subnet that is isolated and requires content filtering for any server that might access the Internet using a browser, the two Netskope deployment methods that would meet this requirement are:

• B. Deploy Data Plane on Premises (DPoP) with a proxy configuration on the servers: Deploying DPoP would allow the isolated servers to connect to the Netskope cloud forcontent filtering through a proxy configuration.This setup would enable the servers to have controlled access to the Internet for content filtering purposes without requiring direct Internet access1.
• C. Deploy IPsec or GRE tunnels in the segment to steer traffic from the servers to Netskope: By deploying IPsec or GRE tunnels, the traffic from the servers can be securely directed to Netskope for content filtering.This method is suitable for environments where servers do not have direct Internet access, as the tunnel provides a secure path for traffic to reach Netskope’s cloud services1.

These deployment methods are designed to work in environments with strict network isolation and provide the necessary content filtering capabilities for servers accessing the Internet.

References: The deployment methods and their suitability for isolated server subnets are based on Netskope’s documentation and resources, which detail various deployment options and their use cases21.

In the given scenario, a user is attempting to upload a file containing sensitive PII and PCI data to Microsoft OneDrive. The Netskope Security Cloud provides real-time data and threat protection when accessing cloud services, websites, and private apps from anywhere, on any device. Based on the exhibit provided, different DLP (Data Loss Prevention) profiles are triggered - DLP-SourceCode, DLP-PCI, and DLP-PII. Each of these profiles has specific actions associated with them; for instance, an alert is generated for Source Code while blocking actions are initiated for PCI and PII data. Since multiple DLP profiles are triggered due to the sensitive nature of the content in the file being uploaded, separate incidents will be generated for each matching profile ensuring comprehensive security coverage and incident reporting.
